Compact Design and Streamlined Installation Improves ESS Payback

This is the final article in a series highlighting the five remarkable design features incorporated into the Orca™ Energy Storage System (ESS) product line design—a design that earned Corvus Energy the Electric & Hybrid Marine Technology 2017 Innovation of the Year award, as well as the BC TIA Technology Impact Award for Excellence in Product Innovation.

This fifth article describes the sleek, modular design of the Orca ESS that has reduced installation connection and commissioning times by up to 80% and installation costs by up to 50%.

 

Three reasons for faster, less expensive installation
This second generation of Corvus Energy’s highly acclaimed ESS incorporates the learned experiences from over six years of ESS commissioning in over 50 vessels in a variety of maritime environments. The three main reasons for lower installation and commissioning costs are outlined below.

  1. Compact Dimensions: Some of the most significant cost savings stem from a roughly 50% volume reduction and 10% weight reduction in the size of the Orca modules due to significantly higher energy density in the battery. Lower volume means that less space needs to be allocated on the vessel for the battery room.
  2. Safety and Thermal Management: There are typically significant cost savings in setting up the battery room. Higher cell-to-heatsink surface area and improved air flow result in a five-fold improvement in thermal management, which enables an air-cooled system to satisfy most use-cases.Further, Orca ESS has passed the Norwegian Maritime Authority’s (NMA) thermal runaway propagation Test 1—the most stringent test—witnessed by NMA and class society DNV GL. The safety, reliability, performance, and cost-reduction implications are outlined in Safety at Sea is the Top Priority for Corvus Energy Orca ESS.

    As a result, design and commissioning of the battery room and its infrastructure is less costly, with significantly simplified sprinkler, ventilation, and class/flag approvals.

  3. Integration and Factory Testing: Commissioning the Orca system itself is also faster and simplified, reducing installation time by up to 80% or about 1 person-week for a typical 1 MWh system. Much of the savings in field commissioning time comes from the Orca design, in which the power loop is integrated into the rack, along with the battery monitoring communications, so that both can be factory-tested.

In his remarks about awarding Orca ESS the Electric & Hybrid Marine Technology 2017 Innovation of the Year award, awards panel judge Martyn Lasek, editor, Ship & Bunker, said, “Battery technology is at the heart of electric and hybrid marine propulsion technology. Corvus is a true leader in this area.”

Rapid Adoption of Orca ESS
Since its introduction in June 2016, Orca ESS has been selected for over 30 projects totaling over 25 MWh, and the technology will only continue to improve the viability of hybrid and all-electric systems in a greater range of maritime applications.

This is the fourth article in a series highlighting the five remarkable design features incorporated into the Orca™ Energy Storage System (ESS) product line design—a design that earned Corvus Energy the Electric & Hybrid Marine Technology 2017 Innovation of the Year award, as well as the BC TIA Technology Impact Award for Excellence in Product Innovation.

The Orca product line consists of two distinct ESS platforms—Orca Energy and Orca Power—each using different battery cell technology with optimized performance characteristics to match high energy demands or high power demands, respectively. In this article, we explore the technology and ideal uses of Orca Power ESS in maritime applications.

Industry’s Highest Discharge Rates
Discharge and charge rates of batteries are specified in a measure called the “C-Rating”. The C-Rating of a battery (or cell) indicates the maximum safe continuous discharge or charge rate. For example, a C-Rating of 10C means it can be discharged at 10 times that pack’s capacity. Continuous and peak C-Ratings are generally specified.

Orca Power ESS can discharge at peak rates of 15C and continuous rates of 10C—rates that simply cannot be attained by any other ESS supplier in the industry.

What are some of the applications that benefit from these high discharge and charge rates? Those with variable loads, says Sean Puchalski, Vice President of Strategic Marketing at Corvus Energy. “The economic benefit of the ESS is derived mostly from load leveling, peak shaving, and spinning reserve. The first two functions in particular are more pronounced in a vessel that must respond to high variation in propulsion loads.”

ESS-Assisted Dynamic Positioning and Peak Shaving Reduces Costs 20-30%
Bjørn-Johan Vartdal, Project Manager at Det Norske Veritas (DNV) agrees that vessels, such as offshore drill platform supply vessels, can benefit from a hybrid-electric system and integrated ESS. “When operating on dynamic positioning, there is a major fuel saving potential. When in harbour, too, the ship should be able to operate on the fuel cell and its battery power alone, which will reduce emissions significantly.”

To maintain the position of the vessel amid wind and waves, thrusters must respond quickly and dynamically. Traditionally, diesel or LNG generators have powered the thrusters, but slow generator ramp rates delay response time. Further, generators are typically sized for peak loads and may often operate in inefficient ranges. Consequently, a hybrid-electric system that can quickly draw high power from an ESS helps to both improve ramp rates and offset peak power demands—a practice known as peak shaving.

The primary benefit of a hybrid system for offshore supply vessels is a 20-30% reduction in fuel consumption and CO2 emissions achieved through smoother and more efficient operation of the generators. Moreover, generators can often be sized smaller to handle base loads as the peak loads will be absorbed by the ESS. So in addition to fuel efficiency, peak shaving may reduce generator running hours and may even negate the need to turn on additional generators.

High C-Rate Means Fast Charging
Let’s not forget that the ESS needs to be charged. Orca Power ESS can charge at peak rates of 13C and continuous rates of 5C, meaning that Orca Power ESS batteries can be quickly charged from shore charging stations and via energy recovery systems.

An example of a shore station ESS that takes advantage of quick discharge/charge using a Corvus ESS is the all-electric Norled ferry, Ampere. The ferry pauses only 10 minutes to unload and load vehicles. The shore ESS at each quay stores energy from the grid and performs a rapid battery-to-battery energy transfers with the on-board ESS while the ferry is docked. The top-up charges the ferry receives after each crossing allows it to make 34 crossing each day before receiving a full charge from the grid overnight.

Due to the quick charge rates, energy can also be recovered and stored in the ESS from port gantry cranes or off-loading equipment on vessels lowering their payload. Again, the high C-Rating means that a significant portion of the potential energy in elevated payloads can be converted into stored energy, further improving energy efficiency and ESS return on investment.

Rapid Adoption of Orca ESS
Whether Orca Power ESS is selected for its high discharge/charge rates and dynamic response, or Orca Energy ESS is selected for its high energy density and low cost per kWh, Orca ESS is a practical and economical solution for an increasing number of marine applications. Since its introduction in June 2016, Orca ESS has been selected for over 30 projects totaling over 25 MWh, and the technology will only continue to improve the viability of our systems in a greater range of maritime applications.

This article is one in a series highlighting the five remarkable design features incorporated into the Orca™ Energy Storage System (ESS) product line design—a design that earned Corvus Energy the Electric & Hybrid Marine Technology 2017 Innovation of the Year award, as well as the BC TIA Technology Impact Award for Excellence in Product Innovation.

The Orca product line consists of two distinct ESS platforms—Orca Energy and Orca Power—each using different battery cell technology with optimized performance characteristics to match high energy demands or high power demands, respectively. In this article, we explore the technology, ideal uses, and three examples of Orca Energy ESS in marine applications.

Unparalleled Energy Density Reduces Cost by 40%
Orca Energy ESS offers a compact design, packing 1.6 MWh in a volume equivalent to a 20 foot shipping container. The key to its compactness is the high energy density of the lithium-ion battery cells in combination with Corvus’ innovative and award-winning battery module and pack designs—energy density that is unparalleled in the industry.

Moreover, the new design resulted in a 40% drop in the cost per kilowatt-hour of stored energy, opening the flood-gates for accelerated adoption of Corvus Energy’s lithium-ion battery energy storage systems.

Longer-Haul Vessels Now Among Ideal Uses
High energy density has made Orca Energy ESS an economically viable energy storage solution for a wide variety of uses. Orca Energy ESS performance is, however, optimized for energy storage uses with relatively constant power loads and discharge rates. As such, the Orca Energy ESS is well suited to electric or hybrid passenger and cargo ferries, tugs, supply vessels, cruise ships, and yachts. Operating at zero or low emissions in harbour and in sensitive marine environments is now more practical and affordable than ever.

Orca Energy ESS is also a viable alternative for spinning reserve, uninterruptible power supply (UPS) or fault ride-through for the entire power system or for subsystems.

Three examples of Reduced Emissions and Fuel Costs:

  1. Viking Princess supply vessel conserves an estimated 1 tonne of fuel per day. Wärtsilä selected Corvus Energy to supply Orca Energy ESS for the retrofit of a second Eidesvik offshore platform supply vessel, the Viking Princess, following the successful retrofit of the Viking Lady. The Viking Princess is a state-of-the-art offshore supply vessel designed to safely service offshore installations in the extremely harsh waters of the North Sea. The 533kWh Orca Energy ESS will be installed on the vessel in a hybrid arrangement. It replaces one LNG genset, approved by DNVGL & NMA as spinning reserve, and will result in one tonne of fuel savings per day.“Corvus Energy, and more specifically the Orca Energy ESS, was selected for its compelling safety, performance and return on investment,” said Dag Håvard Håvardsholm of Wärtsilä. “Based on the innovative approach of Orca and Corvus’ industry leading experience, ship owner Eidesvik has complete trust in this solution.”
  2. Hybrid chemical tanker runs fewer diesel generators. A new hybrid chemical tanker built for Rederiet Stenersen of Norway is the first vessel of its kind to utilize an ESS. Orca Energy ESS integrates with WE Tech Solutions’ hybrid power and propulsion systems, and will allow fewer diesel generators to run for certain operations—improving efficiency, reducing the emissions and lowering noise levels, and making it the most environmentally friendly chemical tanker ship in the Rederiet Stenersen fleet.“Corvus Energy’s industry leadership and experience made our selection of Orca a very straightforward decision,” said Niklas Jakobsson Project Manager at WE Tech. “The innovations Corvus has achieved on cost, safety and performance have created an extremely compelling energy storage solution.”
  3. Polar cruise vessel set for zero emissions. Two new polar expedition cruise vessels are being built for a European expedition cruise operator. Corvus will supply Orca Energy ESS to provide supplemental energy to the vessels in order to improve performance and reduce both operating costs and emissions.Each polar exploration vessel has been outfitted to handle up to 6MWh capacity of Orca Energy ESS to provide operational power. The vessels will be capable of cruising silently and emissions-free on ESS battery power alone into pristine locations, providing its passengers with the experience of exploring some of the world’s most exceptionally beautiful and unspoiled natural surroundings.

Rapid Adoption of Orca Energy ESS
“These latest orders show the viability of energy storage for the hybridization of longer-haul vessels,” said Halvard Hauso, SVP Business Development of Corvus Energy based in Bergen Norway. “As the cost of lithium ion batteries continues to improve we will see more and more applications beyond the traditional ferry and tugboat base.”

Whether Orca Energy is selected for its high energy density and low cost per kWh, or Orca Power is selected for its high discharge/charge rates and dynamic response, Orca ESS a practical and economical solution for an increasing number of marine applications. Since its introduction in June 2016, Orca ESS has been selected for over 30 projects totaling over 25 MWh, and the technology will only continue to improve the viability of our systems in a greater range of maritime applications.

Energy or Power – Corvus Energy Orca™ ESS Product Line Meets Both Differing Demands

Energy or Power – Corvus Energy Orca™ ESS Product Line Meets Both Differing Demands

This is the second article in a series highlighting the five remarkable design features incorporated into Corvus Energy’s Orca™ Energy Storage System (ESS) product line design—a design that earned Corvus Energy the Electric & Hybrid Marine Technology 2017 Innovation of the Year award, as well as the BC TIA Technology Impact Award for Excellence in Product Innovation.

Fundamental to Orca’s design is the recognition that there are multiple uses of ESS systems, and the performance requirements are significantly different depending on its use. “Even among the vessel types that are installing ESS today, there are differing requirements for what the products must do,” explains Sean Puchalski, Vice President at Corvus Energy. “These differences are mostly in terms of whether the vessel needs an ESS that can discharge evenly over an extended period of time (think all-electric ferry) or whether the vessel needs an ESS that can absorb and support large fleeting transient power loads (think offshore supply vessel dynamically positioning next to a drill rig in rough weather).”

The Orca product line consists of two distinct ESS platforms—Orca Energy and Orca Power—each using different battery cell technology with optimized performance characteristics to match high energy demands or high power demands, respectively.

Selecting ESS for High Energy or High Power
Let’s briefly revisit the terms energy and power, which are sometimes used interchangeably … but which are distinctly different. Energy is the “capacity for doing work”, while Power is the “rate of doing work” or the rate at which energy is consumed. The basic unit for energy is the joule (J), while the basic unit of power is the joule per second (J/s), known as the watt (W).

In terms of an ESS for marine vessels, the stored energy or capacity of the ESS is typically measured in kilowatt-hours (kWh) or megawatt-hours (MWh) meaning how much power can be delivered for a specified amount of time.

But, as Puchalski describes, as important for selecting the right ESS is the variability of the load—or demand for power—throughout the vessel’s operation profile and the time that the energy stored in the ESS is being discharged. Is the load relatively constant so that the ESS discharges evenly over time, as in a ferry on a fixed route crossing or an ESS used as battery-backup? Is peak demand intermittent and well above average demand, such as a tug that may spend less than 10% of its time at or near its full bollard pull rating? Or are there transient power loads, such as an offshore supply vessel using thrusters for dynamical positioning to maintain its position next to a drill rig?

Orca Energy ESS is optimized for energy storage uses with a relatively constant power load and discharge rate. It is ideally suited for use with all-electric short haul vessels, and is a viable alternative for spinning reserve, uninterruptible power supply (UPS) or fault ride-through for the entire power system or for subsystems. Due to high energy density, Orca Energy ESS offers a low cost per kWh of stored energy.

Orca Power ESS is an ideal energy source for uses with variable demand. It is designed for seamless response to dynamic power loads, and can deliver power quickly and efficiently to port cranes, charging stations, and offshore supply, exploration and production vessels. Due to extremely high C-ratings, Orca Power ESS offers the industry’s fastest discharge and charge rates.

Economic Benefit Improved with Correct ESS Matching
By correctly matching the appropriate ESS for the operating profile of the vessel and the intended use of the ESS, the economic payback is greatly enhanced—often doubling the return on investment.

In hybrid systems, the primary sources of an ESS’s economic benefit are reduced fuel consumption and lower generator maintenance cost due to efficient operation of fuel-based generators. An ESS can be used for spinning reserve, for instant response to transient loads, and for load balancing through peak shaving and ramping of dynamic loads where there is high variation in propulsion loads. These ESS functions allow generators to run less often and at optimal load for optimum fuel efficiency—resulting in reduced fuel consumption of 15%-75% depending on the application.

Further, the ESS can replace a generator and its associated capital, operating, and maintenance costs when used in fully electric vessels or in hybrid vessels for backup power, including spinning reserve.

Whether Orca Energy is selected for its high energy density and low cost per kWh, or Orca Power is selected for its high discharge/charge rates and dynamic response, Orca ESS is a practical and economical solution for an increasing number of marine applications. Since its introduction in June 2016, Orca ESS has been selected for over two dozen projects totaling over 20MWh, and the technology will only continue to improve the viability of these systems in a greater range of maritime applications.

Safety at Sea is the Top Priority for Corvus Energy Orca™ ESS

Safety at Sea is the Top Priority for Corvus Energy Orca™ ESS

Will safety be compromised as more and more battery vendors and marine propulsion system integrators bid to win a share of the expanding sea of hybrid and electric marine vessels? Corvus Energy, the leader in marine Energy Storage Systems (ESS), has worked hard to achieve the highest standards of safety with its Orca™ ESS, and is the only supplier to carry DNV, Lloyd’s Register, ABS and BV product Type Approvals.

Today is the Day of the Seafarer. In salute to seafarers, and out of intrinsic concern for their safety at sea, we want to review the design practices that Corvus Energy incorporates and the tests we have passed to prove the safety of the Orca™ ESS for hybrid or fully electric propulsion systems.

Geoff Crocker, Director of Product Management & Technical Sales at Corvus Energy, spoke at Nor-Shipping, and David Lokhorst, Corvus Energy’s Vice President of Engineering, spoke at Electric & Hybrid Marine World Expo about the safety features built into the company’s Orca ESS. For those who may have missed the presentations, this article captures the highlights.

The top three technical advancements that improve safety in Corvus Energy’s latest Orca ESS product line are:

  1. Thermal Runaway (TR) Protection
  2. Thermal Management
  3. Electrical Safety and Performance

Thermal Runaway Protection
The best protection from thermal runaway comes from prevention, by selecting a high quality cell manufacturer and designing the battery system with a sophisticated battery monitoring system (BMS), hardware safeties, and good integration with the energy management system (EMS).

However, in the highly unlikely event that a cell fails and its temperature spikes, it is important that adjacent cells do not also experience thermal runaway.

Corvus Energy’s Orca energy storage system design achieves true cell-level thermal runaway isolation, meaning that adjacent cells stay cool without the need for expensive active cooling. Further, The Orca ESS module is designed with internal ventilation pathways to vent gases generated by thermal runaway, and prevent gas from entering the battery room.

Orca ESS passed the NMA’s thermal runaway propagation Test 1—the most stringent test—in September 2016, witnessed by class society DNV GL. The NMA requires tests to verify that when safety systems are deliberately defeated and thermal runaway of a battery module is induced by overcharging, the thermal runaway is limited to a single module and does not spread to other modules in the battery pack. Corvus demonstrated that Orca was designed with a higher level of fault tolerance by eliminating the possibility of thermal runaway spreading to neighbouring cells within a single module.

Thermal Management
The Orca ESS design is optimized for heat-shedding to maintain a uniform temperature across the cell, which enables the cell to operate at its maximum capability. The design incorporates integrated rack fans and active temperature monitoring between cells, which improves reliability and reduces maintenance costs in the long run.

Improved thermal management also means that, typically, air-cooling is all that is required to satisfy marine demands and less battery room infrastructure is needed—both of which reduce system costs.

Orca ESS can also be liquid-cooled in extreme environments and ultra high performance use cases.

Electrical Safety and Performance
The clever and sleek design of the Orca ESS module-and-rack leaves no exposed cables for increased safety during installation and operation. Even the optional air- or liquid-cooling systems are integrated into the rack, resulting in actively cooled connections. Fewer connections, a shorter conductive path, and cooled connections lead to higher reliability and performance, in addition to improving safety.

In addition, safety features incorporated into Orca ESS triggers disconnect at predefined loads, over-voltage or over-temperature. And with voltage isolation of 7.2kV, Orca ESS exceeds Class and Flag standards.

Improved Safety, Better Reliability and Performance, and Lower Cost
While safety is paramount and fundamental to the design of Orca ESS, some of the design features—in particular those for thermal management and electrical safety—also result in overall system cost-savings due to faster installation and lower cost battery room and fire extinguishing system costs. It’s a good Day for a Seafarer when you don’t have to compromise safety for affordability.

Corvus Energy to Display Advances in Industry-Leading Energy Storage Solution at Electric & Hybrid Marine World Expo 2017

Corvus Energy to Display Advances in Industry-Leading Energy Storage Solution at Electric & Hybrid Marine World Expo 2017

At the upcoming Electric & Hybrid Marine World Expo in Amsterdam, June 6-8, Corvus Energy will display the latest enhancement to its Orca™ product lines—Orca Energy and Orca Power—the industry’s safest and most capable Li-ion battery systems for energy storage and electric power applications. “We expect particular interest in our liquid-cooled battery systems that make it possible to discharge and charge at the highest C-rates in the industry,” says Sean Puchalski, VP of Strategic Marketing & Accounts at Corvus Energy.

It was almost a year ago that Corvus Energy was awarded Supplier of the Year at the 2016 Electric & Hybrid Marine Awards. It was the second consecutive year that Corvus Energy had received the award, prompting awards panel judge, John Snyder, editor-in-chief and publisher of Marine Log to declare, “It’s hard to find a hybrid or electric marine power project that they don’t have a hand in.”

The pace has not slowed for Corvus Energy in the past year, with the release of its Orca™ product line and expanded adoption of Corvus energy storage solutions in maritime applications—both on land and at sea.

“We at Corvus Energy are thrilled that we continue to be selected by leading propulsion system partners and shipbuilders who share our vision of cleaner energy solutions,” reports Puchalski. “Since the launch of Orca less than a year ago, we have won 24 deals totaling 15MWh, and the technology advancements in our latest Orca product releases will only improve the viability of our systems in a greater range of maritime applications.”

In the past year, Corvus Energy has cemented its relationship with Scandlines with a long-term agreement to remotely monitor and service the Corvus battery systems on Scandlines hybrid ferries—the world’s largest fleet of newbuilt and retrofitted hybrid ferries.

Corvus Energy also provided the Energy Storage System (ESS) for three cargo ferries: two LNG-battery hybrids for Seaspan Ferries of Canada transporting cargo in the waters of British Columbia, and one hybrid in partnership with Halvorsen Power Systems to operate in Danish waters. “The Orca Energy ESS from Corvus was an extremely compelling solution for this application,” said Hans Petter Heggebø, CEO at Halvorsen Power Systems AS. “By combining industry leading safety, performance and economic feasibility, Corvus has achieved the ultimate maritime ESS with Orca and we really enjoy working closely with the skilled and enthusiastic Corvus team in Bergen.”

The sheer variety of marine applications in which Corvus Energy has been involved in the past year—which include two European polar expedition cruise ships, research and fish farm support vessels in Norway, and a San Francisco Bay area’s Educational Tall Ship—highlight the range of interest in electric and hybrid propulsion systems in waterways around the globe.

On land, maritime ports in China are leading the way in reducing emissions by using hybrid gantry cranes incorporating Corvus energy storage solutions. “Gantry cranes have demanding power requirements, and the compact and rugged nature of Corvus battery systems fits the application well,” say Puchalski. “Offsetting demands on diesel generators, and recovering energy from container lowering, can reduce fuel consumption by 55% to 75% and dramatically reduce emissions.”

Corvus Energy Earns Accolades for its Role in Clean Energy Adoption

Corvus Energy Earns Accolades for its Role in Clean Energy Adoption

Corvus Energy has been named a finalist in the BC Tech Association’s Technology Impact Awards in two categories: Excellence in Product Innovation and Adoption of Technology along with Seaspan Ferries Corporation.

We are seeing a welcome interest and increasing commitment—particularly in Scandinavian countries and recently in Canada—towards cleaner energy sources for marine propulsion systems.

Driven largely by forward-thinking government agencies and visionary vessel owners and shipbuilders, fleets of diesel-powered drives are being retrofitted or replaced with hybrid or fully electric propulsion. The result is reduced combustion of diesel fuel, lower CO2 and other GHG emissions, less particulate air pollution, and quieter operation. “The vision of sustainable energy is core to Corvus Energy’s corporate mission,” says Corvus Energy president and CEO, Andrew Morden. “We are thrilled to be recognized as leaders in this movement.”

Corvus Energy battery systems have been integral to the designs of numerous first-ever and award-winning hybrid and electric marine vessels. Corvus Energy is proud to have collaborated with the following companies to showcase a variety of environmentally progressive energy solutions:

Seaspan Ferries – Canada. Two Seaspan cargo ferries are the first dual-fuel Diesel/LNG and battery energy storage hybrid ferries outside of Europe. Corvus Energy battery systems are used for spinning reserve and power for responsive harbour maneuvering. The innovative hybrid propulsion system reduces fossil fuel emissions and greatly improves operational efficiency and safety. Corvus Energy and Seaspan are finalists in the category of Adoption of Technology for the 2017 BC Technology Impact Awards.

Corvus Energy as one of the NCE Maritime CleanTech companies to showcase at the Nor-Shipping Disruptive Sustainability Hall

http://www.nor-shipping.com/press-release-nce-maritime-cleantech-companies-flock-shipping-disruptive-sustainability-hall/

Press release: NCE Maritime CleanTech companies flock to Nor-Shipping Disruptive Sustainability Hall

Seven of the key players in the Norwegian Centres of Expertise (NCE) Maritime CleanTech cluster have signed up for Nor-Shipping 2017’s ground-breaking Disruptive Sustainability exhibition hall.

Bostek, Corvus Energy, NorthSea Container Line, Servogear, The Switch Norway, Wärtsilä and Westcon Power & Automation will all showcase their abilities in a unique space that aims to challenge convention and embrace innovation, priming the industry to tackle the challenges and opportunities that lie ahead.

Nor-Shipping, the leading maritime event week, taking place across a series of venues in Oslo and Lillestrøm from 30 May to 2 June, has dedicated the whole of its Hall A to the concept. In doing so it hopes to open the industry door to new ways of thinking, working together and innovative technologies – taking ideas and influence from outside arenas, such as the tech and business sectors, and building a platform for fresh collaborations.

According to Sofia Fürstenberg, Nor-Shipping’s Project Manager for Disruptive Sustainability, NCE Maritime CleanTech is the perfect partner for this new philosophy.
“This cluster, situated on the West Coast of Norway, is a global leader in developing energy-efficient and environmentally friendly technologies that have the potential to transform sea transportation,” Fürstenberg notes. “Through a unique collaborative approach, where there is a cross fertilisation of ideas and opportunity, they arrive at solutions that impact upon every link in the maritime value chain, from subsea, to marine and throughout the energy sector.

“They will deliver a range of memorable takeaways for the 35,000 people that visit Nor-Shipping, showcasing green hybrid and electric solutions, alongside technology that enables increased digitalisation and the shift towards autonomy. For us, this cluster, which won the prize as Norway´s leading innovation environment in 2016, encapsulates the concept, opportunity and huge benefits of Disruptive Sustainability.”

NCE Maritime CleanTech will join a range of high profile exhibitors that have already booked their place in the 1245 sq. m hall, including DNV GL, DNB and Siemens. Billed as a dark, immersive and uniquely engaging space, it’s an experience that Hege Økland, CEO of NCE Maritime CleanTech, is looking forward to.
“This concept is perfect for our cluster,” she comments. “We intend to showcase sustainable solutions that disrupt industry norms, pointing the way towards new possibilities for the future maritime sector.”

“Cluster collaboration is decisive for green innovation. We represent companies that have developed the first zero-emission car ferry in the world, the first hybrid-OSV, and, later this year, a new solution for inductive charging. And that’s just mentioning a few of our collective achievements. ‘Seeing is believing’ and at Nor-Shipping we aim to present our ground-breaking solutions in a way that will inspire, engage and connect with today’s, and tomorrow’s, key maritime players.”

Alongside Hall A, Nor-Shipping offers a further five themed halls, covering the full spectrum of maritime products, services and solutions. In total, almost 1,000 companies will be showcasing themselves to the industry, future talent and shipping value chain stakeholders.

Nor-Shipping is also presenting a diverse and powerful speaker and event line-up, with a packed programme of business and social gatherings across city centre Oslo and its facilities in Lillestrøm.
